The Kremlin declined on Tuesday to confirm that Ukrainian forces had again launched US-provided long-range ATACMS at Russia this week but blamed Washington for escalating the conflict nonetheless.

Moscow and Kyiv have been ratcheting up their drone and missile broadsides, with Ukraine recently firing US long-range missiles at Russia and the Kremlin retaliating with an experimental hypersonic missile.

The barrage came as ambassadors from Ukraine and NATO's 32 members were due to meet in Brussels over Russia's firing last week of the intermediate-range missile on the city of Dnipro.

"During the night attack, the enemy launched a record number of Shahed strike unmanned aerial vehicles and unidentified drones," the air force said Tuesday, referring to Iranian-designed drones and putting the overall number fired at 188.

The air force said it had shot down 76 Russian drones in 17 regions, while another 95 were either lost from their radars or downed by electronic jamming defensive systems. It did not specify what happened to the remainder.

Moscow also fired four Iskander-M ballistic missiles, the air force said.

"Unfortunately, critical infrastructure facilities were hit, private and apartment buildings were damaged in several regions," a statement said.

- Explosions in Kyiv -

AFP journalists heard explosions ring out over the capital, while Kyiv city officials said the air alert had lasted five hours and 10 Russian drones were shot down there.

In the western Ternopil region, which is among those spared the worst of the fighting, authorities said drones had damaged a "critical infrastructure facility," without elaborating.

They said however that the attack had disrupted electricity in the city of Ternopil and surrounding towns, and that engineers were working to stabilise supplies.

Putin had said the new missile attack last week was in response to Ukraine firing weapons supplied by the United States and Britain into Russia.

The Kremlin leader warned that Moscow felt it had the right to hit military facilities in countries that allow Ukraine to use their weapons against Russia.

Ukrainian President Volodymyr Zelensky last week called the strike "the latest bout of Russian madness" and appealed for updated air-defence systems to meet the new threat.

Kyiv says it hopes to get "concrete and meaningful outcomes" after calling the meeting of the NATO-Ukraine Council.

But diplomats and officials at NATO have played down expectations for any major results from the consultations on Tuesday afternoon at the alliance's Brussels headquarters.

The most that is expected is a reiteration of NATO's earlier insistence that Moscow's deployment of the new weaponry will not "deter NATO allies from supporting Ukraine".

The meeting "provides an opportunity to discuss the current security situation in Ukraine and will include briefings from Ukrainian officials via video link," a NATO official said.

The Kremlin dismissed the meeting saying it was unlikely any significant decisions would be taken.

On the battlefield, Ukraine's fatigued troops are struggling to halt advances by Russian forces in the east of the country.

Russia said Tuesday its troops had captured another village in the Kharkiv region, in an area where the front line had been relatively stable until recently.

The defence ministry said its units had "liberated" the settlement of Kopanky," a village near the Ukrainian-held city of Kupiansk that was previously captured by Russian forces at the start of the 2022 offensive before being re-taken by Ukraine later that year.

Moscow also on Tuesday confirmed it had detained a British man it captured fighting for Ukraine in Kyiv's offensive into Russia's western Kursk region.

A court in the region said it had on Monday ordered James Scott Rhys Anderson be remanded in custody, alleging he had "participated in armed hostilities on the territory of the Kursk region".
